Why are ZLD processes on the rise? Access to water is no longer assured. Cape Town narrowly averted “Day Zero” amid intense public scrutiny during a 2018 drought. In June 2019, the 11 million residents of Chennai, India, endured a day without drinking water, and in 2020, the towns of Stanthorpe and Clifton in Queensland, Australia, both experienced water depletion. These incidents are not isolated and are projected to escalate as climate change effects intensify. When faced with systemic risks to economic growth and public health, the economic implications of…

eawater

By Manoj Nainani, Executive Director, Egis India Over the years, growth of population, expansion of industry and infrastructures has resulted in accelerated depletion of the natural water supplies and created water stress regions around the world. Further, to preserve natural resources from overburdening and pollution; stringent environmental regulations are being enforced. This requires additional technology interventions prior to waste water discharge and to undertake water management practices. Zero Liquid Discharge (ZLD) is a comparatively recent development in waste water treatment that totally eliminates requirement of waste water discharge to the…
